Fractional flow reserve (FFR) has become the gold standard for invasively assessing the functional significance of coronary artery disease (CAD) to guide revascularization. The amount of evidence supporting the role of FFR in the cardiac catheterization laboratory is large and still growing. However, FFR uptake in the daily practice is limited by a variety of factors such as invasive instrumentation of the coronary artery that requires extra time and need for vasodilator medications for hyperemia. In this review, we describe the details of wire-based alternatives to FFR, providing insights as to their development, clinical evidence, and limitations.

Background: In patients with coronary artery disease (CAD) and/or myocardial infarction (MI), anemia is associated with an increased risk of adverse cardiovascular (CV) outcomes. Transfusion goals in such patients remain unclear.

Study Question: A meta-analysis of the available randomized controlled trials (RCTs) was conducted comparing restrictive and liberal transfusion strategies in patients with symptomatic CAD/MI.

Coronary artery disease (CAD) is the leading cause of death worldwide. Acute coronary syndrome (ACS) encompasses a spectrum of diagnoses ranging from unstable angina pectoris to myocardial infarction with and without ST-segment elevation and frequently presents as the first clinical manifestation. It is crucial in this scenario to perform a timely and comprehensive assessment of patients by evaluating the clinical presentation, electrocardiogram and laboratory diagnostics using highly sensitivity cardiac troponin in order to initiate a timely and risk-adapted continuing treatment with immediate or early invasive coronary angiography.

Data on outcomes of extracorporeal membrane oxygenation (ECMO) are limited in patients with pulmonary atresia intact ventricular septum (PAIVS). The objective of this study was to describe the use of ECMO and the associated outcomes in patients with PAIVS. We retrospectively reviewed neonates with PAIVS who received ECMO between 2009 and 2019 in 19 US hospitals affiliated with the Collaborative Research for the Pediatric Cardiac Intensive Care Society (CoRe-PCICS).

Purpose: To assess the efficacy of bolus injections of landiolol hydrochloride as premedication in coronary artery CT angiography (CCTA).

Methods: The study population consisted of 37 patients (17 female; median age, 56 years; IQR, 19 years; range, 19-88 years) who underwent CCTA after intravenous injection of landiolol hydrochloride due to a heart rate > 60 bpm. Landiolol hydrochloride was administered in a stepwise manner until a heart rate of ≤ 60 bpm was achieved or a maximum dose of 60 mg was reached after six injections.

Objectives: The use of deep learning models for quantitative measurements on coronary computed tomography angiography (CCTA) may reduce inter-reader variability and increase efficiency in clinical reporting. This study aimed to investigate the diagnostic performance of a recently updated deep learning model (CorEx-2.0) for quantifying coronary stenosis, compared separately with two expert CCTA readers as references.
